Keeping Up With The Kardashians star Kylie Jenner has reportedly recorded a song with her rumoured boyfriend Tyga and rapper Iggy Azalea in a bid to launch her music career.

Music website Rap Dose were the first to report that Jenner, 17, has collaborated with Rack City rapper Tyga and Australian hitmaker Azalea on a track titled Forever Real. The publication tweeted a photo of the song's artwork on Monday (23 March), showing the reality star wearing a revealing swimsuit.

Speculation about Jenner's music career has circulated since September 2014, when a source claimed the E! star wanted to become "the next Katy Perry."

The insider told Radar Online at the time: "Kylie has found her calling in life - to be a singer! She is in training right now with vocal coach and producer, Tim Carter. Kylie is now working on her first single! She is telling everyone that she knows she is going to be the next Katy Perry."

According to the source, Kris and Bruce Jenner's youngest daughter turned to music when her older sister Kendall Jenner started making waves in the fashion industry.

"She realised that she can't compete with Kendall when it comes to modelling. So she has chosen to turn to music. The whole family is really supportive of the decision, and Tim has already been to Kris' house to start the lessons!" the source claimed.

Despite the mounting reports, Jenner denied that she was trying to become a pop star last December when slamming false rumours, tweeting:

The artwork for Forever Real appears to have been photographed earlier this week as Jenner shared several images on Instagram of herself wearing the same outfit.

Tyga, 25, was recently forced to deny reports that he is dating the teenager, telling Power 105.1's Breakfast Club that they are "just friends".
